Re: [R] colour highlighting inputs and outputs in the R terminal?
that's an old thread but checkout the colorout package - it is awesome and it does exactly what you're asking for ! http://cran.r-project.org/web/packages/colorout/ -- View this message in context: http://r.789695.n4.nabble.com/colour-highlighting-inputs-and-outputs-in-the-R-terminal-tp1565865p4634653.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

I am looking for something similar to what GUIs provide, such as JGR and (I think) the Windows R GUI: colouring all inputs in red, and all outputs in blue. All this in a colour-aware console (in my case, on Linux). I've been looking into xterm256 and highlight, but I am sofar unable to do with them what I would need. The closest I get to is with style() in xterm256: require(xterm256) cat( style( hello world, bg = black, fg = blue), \n ) hello world The text will appear blue. What I would want to achieve, however, is to be able to define some global options for input fg and bg colours, and output fg and bg colours. Then, for any command that I would execute, say `mean(1:5)', I would get: mean(1:10) ##in red [1] 5.5 ##in blue summary(1:5) ##in red Min. 1st Qu. MedianMean 3rd Qu.Max. ##in blue 1 2 3 3 4 5 ##in blue Does anyone know a way to do this? Thank you Liviu Hi Liviu, I was not aware of Romain's xterm256 package, but from a quick review of the manual, it would appear to not support an automated syntax highlighting capability. One seems to need to explicitly print output to the console using his functions to be able to colorize it. That's right, xterm256 is for manual formatting. What Liviu wants is not impossible to achieve --- it has been done for python for example [1] --- but would require some considerable effort, using for example ncurses [2] . Romain [1] http://bpython-interpreter.org/home/ [2] http://www.gnu.org/software/ncurses/ Having used R on Windows, Linux and now OSX over the past 8+ years, I initially used ESS (http://ess.r-project.org/) on Windows and stayed with it on each subsequent platform. The terminal consoles are fine for quick and dirty coding and I will frequently use the terminal on OSX to test code for replying to a post here.

In the most basic implementation, you can write your code in the editor and copy and paste it to the R console. With tighter integration, such as ESS, you can have split windows, with R code in one frame (say the upper half of the application window) and the R console running in an other one (say the lower half), both of which support R syntax highlighting. With a quick few keystrokes, you can submit the entire R code frame to the console or highlight sections of code and just submit that.

Re: [R] colour highlighting inputs and outputs in the R terminal?
Liviu, if you use Emacs + ESS, that provides colour highlighting. You can also have a script file alongside so that you have a saved command history in an R source file. See http://ess.r-project.org/ to get started. - Try http://prettygraph.com Pretty Graph , the easiest way to make R-powered graphs on the web. -- View this message in context: http://n4.nabble.com/colour-highlighting-inputs-and-outputs-in-the-R-terminal-tp1565865p1565909.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

From the feedback on r-help it seems that Emacs + ESS is the tool of choice for expert users. I have sofar preferred to avoid ESS (for various reasons) and recently settled for Geany, a more lightweight solution. I'm quite comfortable with what it offers, among others: syntax highlighting, an embedded terminal, a binding that sends current line or selection to the terminal for execution and, a personal favourite, a Tasks plug-in that helps to keep an overview of the structure of the document via specific comments. From the features missing, most I'd like to have some kind of automated syntax highlighting in the embedded VTE. Thank you for the ESS description; I'll give it a try one day, but not quite not yet.
